Users should suitable centrifuges according to the application occasions, material properties other factors to achieve the expected intention. The manufacturer of horizontal screw centrifuge tells you that there are three problems that need to be paid attention to when selecting the type:
1. Anti corrosion function: the materials separated the centrifuge generally have certain corrosivity. It is necessary to reach the requirements of corrosion resistance for the materials touching the materials, so as to ensure safe use.
The data types of structural parts (304, 321, 316, 316L, duplex stainless steel 2205), sealing ring, gasket raw materials, surface treatment methods (plastic lining, rubber lining, surface spraying Halar), filter cloth raw materials shall be confirmed during model selection. The manufacturer can be informed of the material properties (chemical properties, separation temperature, etc.) during selection, so that the manufacturer can make suggestions on the selection of centrifuge raw materials according to the characteristics of the separated medium, indicate them in the order to ensure the anti-corrosion requirements of the centrifuge.
2. Explosion proof function: the centrifuge should have explosion-proof function if the processed materials ( environment) contain flammable explosive substances such as organic solvents. The explosion-proof function shall be confirmed according to the explosion-proof requirements (grade) of the process. In the past two years, most of the explosion-proof occasions only proposed to be equipped with explosion-proof motors, most of the occasions the processed substances were suspected to contain organic solvents, such as solvents, put forward the requirements of nitrogen maintenance. In fact, in order to realize the real explosion-proof of centrifuge, various methods should be adopted in mechanical, electric control, accessory equipment other aspects, such as:
Electric control system: explosion-proof barrier, non touch energy consumption braking system, electrostatic grounding, explosion-proof automatic control.
Mechanical system: explosion-proof motor, explosion-proof lamp, anti-collision method, anti-static drive belt.
Explosion proof accessories: nitrogen maintenance device, nitrogen online detection, on-site explosion-proof control button.
Therefore, in the case of explosion-proof requirements, the user shall indicate the separated medium, explosion-proof requirements grades, equip corresponding devices adopt appropriate methods to meet the explosion-proof requirements when ordering.
